- transmit a message from the transport vehicle to the construction machine when the transport vehicle approaches the construction machine;
- and
- responsive to the message, to transmit from the construction machine to a reception and display device arranged at or in the transport vehicle one or more of:
- first data comprising the image data;
- second data determined from the image data;
- and
- third data comprising one or more detected operating parameters of the milling machine, data determined or derived from the one or more detected operating parameters of the milling machine, and/or data relating to milling material loaded onto the transport vehicle.
